Johnson was arrested Monday and is being held at the Polk County Jail where he faces arraignment Tuesday for attempted murder, conspiracy to commit murder, unlawful use of a weapon, felon in possession of a firearm and reckless endangering.

Bail was set at $217,500.

Witnesses identified Johnson and Scott Newton, 31, of Mill City--who also goes by "Scotty" and the nickname "Sidewinder"--as two suspects who threatened the man at the waterfall on July 8.

Newton remains at-large, police said.

Sheriff's officials said they received reports the two men were at the falls between Parry Road and Mitchell Street and threatened a man with .45 caliber semiautomatic pistols with silver slides and black handles.

The men, police said, then drove to Sheldon Avenue near Frost Road and allegedly shot numerous rounds at a home; a resident returned fire and chased the suspects as they fled into Falls City, the office said.

Police said the chase continued through town, and the suspects fired back at the pursuing vehicle while passing Falls City High School on North Main Street.

The resident gave up the chase when he saw a sheriff's deputy and reported the incident.

No one was injured in the shooting or the chase, the sheriff's office said.

Anyone with information on the whereabouts of Scott Newton is asked to Det. Sergeant Mark Garton of the Polk County Sheriff's Office at 503-623-9251.
